Simple way to help Cass' ult

Instead of having a (relatively) long buildup for her stun, which most people can easily turn away to avoid, make it extend during the cast time, so that anyone who looks during the duration is stunned for the the duration and 2 seconds after. I would still like you to alter her in some way, but this would at least help her to deal with junglers and be more of an asset in team fights.
